Check out the recent Huffington Post article The
Big Password Mistake That Hackers Are Hoping You'll Make by
Jeff Fox that talks about the need to "avoid a little-known
mistake recently uncovered by password researchers" (i.e., the
overuse of common password patterns (or topologies) by users as
they create their passwords). This article references some of
the conclusions that came out of our PathWell (Password Topology
Histogram Wear-Leveling) project, which was sponsored by DARPA
(Defense Advanced Research Projects Agency) in 2013 under its Cyber
FastTrack program. Stay tuned for more PathWell-related news as we
are preparing to release the software developed for that project
in the near future.
